Abstract

Intended is to prevent the output cable of a magnetic sensor, even if tensed, from coming out of a sensor unit. The output cable (16c) of the magnetic sensor (16a), which is derived in the tangential direction of an arcuate sensor holding unit (15a) formed in an annular core bar (15) from a sensor unit (16) mounted in the sensor holding unit (15a), is fixedly molded in a mold resin (17b) which is fixed in a through hole (15c) formed in the sensor holding unit (15a) near the sensor unit (16). As a result, the output cable (16c) is prevented, even if tensed, from coming out of the sensor unit (16).
